Research Summary:Steven Goodreau is an Assistant Professor in the Department of Anthropology. His research interests lie in understanding human infectious disease dynamics through the use of social network analysis, statistical demography, and population genetics.
Goodreau applied methods from mathematical epidemiology to a study of men's sexual behaviors and networks in urban Peru. This work highlighted the important effects of role versatility on the HIV epidemic among men, a phenomenon which has received little attention in prevention efforts. He has extended this research to consider the persistent differences in HIV epidemics between homosexual and heterosexual men in the US, highlighting the degree to which this differential can be explained by demographic and biological, rather than behavioral, factors.
Goodreau is engaged in developing new statistical models for the analysis of social networks. These methods allow the researcher to test hypotheses about the processes that generated observed social network structure, and to consider the higher-order network patterns that emerge from local social behaviors. He is currently applying these models to networks of high school friendships. Using similar models, Goodreau has also examined the role that network structure can play in shaping the neutral evolution of HIV, and the degree to which phylogenetic approaches to reconstructing pathogen dynamics are sensitive to this network structure.
